Instructions
Run back and fourth to dodge Pinky's snowball attack as soon as the battle begins. She'll throw six snowballs before slowly moving her robot ghost into another position. Press "X" to jump over any snowballs that get too close.
Charge up your Rev Run immediately after clearing the sixth snowball. Aim for the center of Pinky's robot face and release the button. Pac-Man smashes into Pinky's face, damaging her. You should be able to land two hits before she starts throwing snowballs again.
Repeat Steps 1 and 2 until Pinky's life level gets low. She'll eventually fly over your head and try to freeze you with her exhaust.
Dodge around the platform as she flies overhead. After a couple of swoops, she'll move back into position next to the platform. Rev Roll into Pinky a couple more times to defeat her and end the battle.
